摘要： A lancet device comprises a hollow housing defining a cavity and having a proximal end and a distal end. It also comprises a slider slidable at least partially within the cavity of the hollow housing along a longitudinal axis from an outward position to a pushed position. The slider extends outside of the cavity beyond the proximal end of the hollow housing when it is in the outward position. The lancet device also comprises a needle holder holding a lance. The needle holder is rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position. When the needle holder is in the initial position, the slider is in the outward position. When the needle holder is in the extended position, the lance extends outside of the cavity beyond the proximal end of the hollow housing. The sliding of the slider from the outward position to the pushed position urges the needle holder to the extended position. There is also a first biasing member positioned within the hollow housing at the distal end. The first biasing member exerts a biasing force against the needle holder toward the proximal end when the slider is moved to the pushed position. A second biasing member can be present in the lancet device.

摘要翻译： 刺血针装置包括限定空腔并具有近端和远端的中空壳体。 它还包括滑动件，滑块至少部分地在中空壳体的空腔内沿着纵向轴线从外部位置滑动到推动位置。 当处于向外位置时，该滑块在中空壳体的近端之外延伸超过该空腔的近端。 柳叶刀装置还包括保持喷枪的针架。 当从初始位置移动到延伸位置时，针保持器可沿着纵向轴线旋转并可平移。 当针架处于初始位置时，滑块处于向外的位置。 当针保持器处于延伸位置时，喷枪延伸到空腔外部超过中空壳体的近端。 滑动件从向外位置滑动到推动位置，促使针架保持在伸出位置。 还有一个位于远端的中空壳体内的第一偏置构件。 当滑块移动到推动位置时，第一偏置构件朝向近端施加抵靠针保持器的偏置力。 第二偏压构件可以存在于刺血针装置中。
